I refer you to Noah's links on the matter. (and note you've looked). Again this is common knowledge , at least amongst those of us who have bothered to follow this over the years. |

This is what you invariably get as DDT and it's derivatives (on breaking down) are very environmentally persistant. The stuff hangs about in the water, the soil for many years. Aromatics are generally very durable in the environment. The vectors are therefore exposed to it over long periods and so have evolved considerable resistance to DDT greatly reducing DDT's effectiveness. It is this environmental persistance and it's biological effects that were DDT's undoing. |

Similarly, PCBs have been found in the fat of polar bears thousands of miles from anywhere where they would be used. It's a persistent chemical that doesn't break down and actually accumulates toxicity in living things. |

How do you prove something is common knowledge ? :rolleyes: (without a statistically valid sample poll of the community). Can you prove it is not common knowledge amongst informed lay people ? |

You're sidestepping again. Provide one itsy bitsy little paragraph from a reputable source that says DDT is now useless as an insecticide. Do not provide a link to a page that says DDT is less effective with overuse or mismanagement Do not provide a link to a 10,000 page essay where only one paragraph is relevant, quote said paragraph instead Do not provide a link and say it proves your point, when it in fact it says something completely different. One little paragraph will do it |

http://www.budsir.org/Toward/2_religion_6.htm Then there was the case of DDT. At that time it was thought that with DDT, our problems with the insect world were over – ants, mosquitoes ... all gone. We thought we could eradicate these creatures and no longer have to be bothered by them. Many years later it was found that DDT was carcinogenic, an insidious substance which could prove fatal even to humans. What's more, while the humans were suffering ill effects from the drug, the insect population was becoming immune to it. In time it became useless as an insecticide, and was more likely to kill the human beings. Many countries have banned the use of DDT, but Thailand is still using it, even now. |

Hey, you weren't specific. You just asked for a paragraph stating DDT is useless now.

With all due respect, and I do mean that, I am done with the my source is better than your source fights. You asked, I provided. I got nothing to prove here. |

May the source be with you
Actually, I dont think we were in disagreement, you were mainly pointing out that DDT is nasty, which is true, I was mainly responding to Spongebath who I think was claiming DDT was useless, actually I'm not sure what he was claiming, he kept changing his mind. DDT is nasty, but the whole point of this thread was that its use is far less nasty than not using it, well in terms of no. of deaths anyway |

I wouldn't say it's useless, but I would say that the drawbacks certainly outweigh the benefits, and it is true that there are a number of species that have developed immunity to it, so in that sense it is useless against them. |
